Abstract
The paper presents the calculation results of local pressure loss coefficient in three different models of a gate valve in their two opening positions. The study was carried out on ice slurry with the mass fraction of ice particles of 30%, 25%, 20%, 15%, 10% and 5%. The slurry is considered to be the Bingham Plastic liquid within this study and the local loss coefficient data were provided thanks to the obtained results of the local resistance calculations in the fittings tested in the experimental investigation. The transitional behavior of ice slurry has been detected. The value of the local pressure loss coefficient decreases firstly up until transition point then it remains constant in the turbulent flow regime. The ice crystals content directly determines its value, as the larger ice mass fraction in the mixture, the greater value of the loss coefficient. Declining opening position of the gate valves results in decreasing the value of the loss coefficient data in relation to the Reynolds number for Bingham liquid.
